盾构管廊不减压到站接收技术及施工要点

城市地下管线是城市重要的基础设施,是对城市各功能区各类管线基础设施的有机连接。论文以实际工程为背景,从盾构到达前准备工作、节点井到达端头加固、洞门破除及密封、接收托架和接收导轨安装、盾构机接收参数几个方面对盾构法综合管廊工程的不减压到站接收技术及施工要点进行总结,为相关设计、施工及管理人员提供了有益的参考,对盾构法综合管廊工程建设具有理论和现实意义。

Reception Technology and Construction Points of Shield Tunnel Arriving at the Station without Decompression

Urban underground pipelines are important urban infrastructures,and they are an organic connection to various pipeline infrastructures in various functional areas of the city.Taking the actual engineering as the background,from the preparation work before the shield arrives,the reinforcement of the end of the node well,the destruction and sealing of the tunnel door,the installation of the receiving bracket and receiving rail,and the receiving parameters of the shield machine,the non-decompression arrival reception technology and construction points of the corridor project are summarized,which provides a useful reference for relevant design,construction and management personnel,and has theoretical and practical significance for the construction of the shield tunnel comprehensive pipeline project.
